Session 4 : Enoncé

Code for download: session4_start.tar.gz

Exercise:

• Explore processes defined for proton, e-, e+, gamma particles via UI commands and add these commands in run.mac.
• Add a possibility to select any Geant4 physics list using G4PhysListFactory class.
  • Check availability of the physics list via
    G4bool IsReferencePhysList(const G4String& physListName);
    See basic/B4/B4a/exampleB4a.cc how to define optional arguments in main function.
• Set particles production thresholds (cuts) via Geant4 command in run.mac.
  See setCut* commands in /run directory.
• Define a region in EM calorimeter with lower production thresholds than the default ones.
  See in DetectorConstruction class in examples/extended/electromagnetic/TestEm8 how to define a region with production cuts.

Exercise ++:

The exercises marked as ++ are optional; they are recommended for participants who have already some experience with Geant4 and get some time left for practicing more than the basic exercise proposed above.

• There is no complementary exercise for this session.
